ADJUSTABLE SHOE AND ZBOQT TREE.

Specification of Letters Patent. Patented Feb, 14, 1922,

Application filed March 9, 1921. Serial No. 451,060.

and Boot Trees, of which the following is a specification.

This invention relatesto boot-trees for use in maintaining boots inpropcr shape.

The invention has for an object to provide an improved. form of device for expanding the tree in the boot or shoe.

For further comprehension of the invention, and of v the objects and advantages thereof, reference will be had to the following description and accompanying draw-- ings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

Fig. 1 of the drawings, is a plan view of a boot tree constructed according to the invention.

Fig. 2 is a side view thereof.

Fig. 3 is a fragmentary side view with the parts adjusted to a different position from that shown in Fig. 2. v

Fig. 1 is a transverse section on the line lt-41 of Fig. 1.

As here shown my improved boot tree is divided into a main body 10, comprising the instep or toe portion, and a heel 11, these parts being capable of longitudinal adjustment with respect to one another. Extend ing longitudinally between these parts 1U and 11, adjacent the bottom thereof, is a rod 12 which engages slidably at opposite ends in sockets 13 and 14:, formed in the parts 10 and 11 respectively.

Mounted upon this rod 12, midway be tween opposite ends thereof, is a verticai screw 15 which has a swivel connection as at 16 with the rod and extends upward between the parts 10 and 11 of the tree. To facilitate the connection of the screw to the rod the latter may be recessed on opposite sides to present a flat intermediate portion 12 with which the end of the screw en- The screw may have an eye 17 gages. formed on its upper end which may serve as a handle or may be used to receive any suitable leverage implement which it may be desired to employ.

The upper and lower portions of the screw 15 are oppositely screw threaded as shown and upon these oppositely screw threaded portions are disposed a pair of nuts 18 and 19. Pivotally connected at one end to the nut 18 are the forwardly and rearwardly extending pairs of toggle bars 21 and 22 respectively, which project into the instep portion 10 and heel portion 11.

Formed in the heel portion'll are a pair of longitudinal slots which extend entirely through the part 11 from top to bottom thereof and rearwardly a distance from the forward face thereof, these slots accommodating the bars 22 which are hinged at their rear ends to a pin 2 1 fixed in the part 11.

Formed in the front part 11 of the tree are another pair of longitudinal slots 26 which extend from top to bottom of the part ll and forwardly for a distance from the rear face thereof. These slots ac commodate the bars 21 which are hinged at their forward ends to a pin 27 adjustable in this part 10 as will be presently pointed out.

Pivotally connected at one end to the other nut 19, are the forwardly and rearwardly extending pairs of toggle bars 30 and 31 respectively. The bars project at their forward ends into the slots 26 and are pivotally attached to a pin 32 also adjustable in the forward part 10 of the tree. The bars 31 project at their rear ends into the slots 23 and are pivotally attached to a pin 34 fixed in the heel portionof the tree.

To provide for adjust-able connection of the pins 27, 32 with the part 10 of the tree, whereby the length of the latter may be varied I provide the latter with the horizontal slots 35 and 36 which extend from side to side therethrough, these slots having the longitudinally spaced angular offsets, 37 and 38 respectively which extend upwardly and forwardly from the main slots 35 and 36, the pins 27 and 32 passing freely through these slots and having suitable heads on their ends which serve both as finger grips and to prevent displacement of the pins transversely in the tree.

The part 10 of the tree may be arranged to receive any protruding member such as 40 to press out special parts of the shoe as desired.

It is believed that the manner of use of my improved shoe tree will be apparent from the foregoing description. When the screw 15 is rotated the toggle bars will be caused to swing on the pins 24, 27, 32, 34, by reason of the travel of the nuts 18 and 19 on the screw, and will either draw the parts 10, 11 together or move them apart as they vary their angular position. The tree can be readily adjusted to large or small shoes by positioning the pins 27, 32 in the desired ones of the slot offsets 87 and 38.

Having thus described my invention what I claim as new and desire to protect by Letfers Patent of the United States is as folows:

1. A boot tree comprising a pair of relatively extensible parts, a horizontal rod extending freely at its ends into sockets in the respective parts, a screw swiveled on said rod, and pairs of toggle barsconnected at one end to the respective parts, and adapted for operation by the said screw.

2. A boot tree comprising a pair of relatively extensible parts, a horizontal rod extending freely at its ends into sockets in the respective parts, a screw having right and left hand threaded portions swiveled on said rod, nuts on the respective screw portions, and toggle bars connected to the said nuts and the respective parts of the tree.

3. A boot tree comprising a pair of relatively extensible parts, a horizontal rod extending freely at its ends into sockets in the respective parts, a screw having right and left hand threaded portions swiveled on said rod, nuts on the respective screw portions,

toggle bars connected to the said nuts and the respective parts of the tree, and means providing for an adjustable connection of one of the said parts with its toggle bars.

4:. A boot tree comprising a pair of relatively extensible parts, a horizontal rod extending freely at its ends into sockets in the respective parts, a screw having right and left hand threaded portions swiveled on said rod, nuts on the respective screw portions, toggle bars connected to the said nuts and the respective parts of the tree, and means providing for an adjustable connection of one of the said parts with its toggle bars, said means comprising slots formed in said part and each having a series of angular offsets, and pins passing through the toggle bars and adapted to engage in any one of the said offsets.

Signed at Detroit, in the county of Wayne and State of Michigan this 5th day of March A. D. 1921.
